To what extent is the Big Lie an example of the Mandela effect?

I saw a bumper sticker on a car up near the fringes of Boebert Country yesterday that said something like “Audit the Elections.”

This got me wondering about the extent to which the belief that elections are being stolen from Republicans by nefarious conspiratorial forces is:

(a) Sincere, as opposed to vice signaling; and

(b) Has by this point morphed to some extent into an example of the Mandela effect, i.e. when a collective confabulation becomes pervasive regarding some historical fact.

A less disturbing example of this:

They are pronounced the same, but even die-hard fans of the series swear it was spelled “-stein.” But let’s be real, was anyone ever really skilled at reading script as a kid?

What’s interesting is that some people, apparently sincerely, develop theories of alternate universes in which their false memory was correct. The progenitor of the Mandela effect was a “paranormal researcher” who believed this explained why she and large numbers of other people remembered Nelson Mandela dying in prison in the 1980s.

Now I don’t doubt that a lot of supposed acolytes of the Big Lie don’t actually believe it, or perhaps more commonly are indifferent to whether it’s true or not: They’re just signaling the beliefs that are necessary to be members of the group.

But I suspect quite a few are by now in the grip of confabulated mass delusion, that includes things like seeing some prominent Democrats admit on TV that the election was stolen, hearing various states Biden “supposedly” won being called for Trump on election night etc.
